postfix lehnt Annahme lokaler E-Mails ab - User unknown in local recipient table.

[Anton Blau]

Hallo,

mein postfix nimmt E-Mails an, die er an dem Smarthost (mail.gmx.net als
smarthost) weiterleitet, er verweigert aber die Annahme von E-Mails, die
er an die bestehenden lokalen Postfächer zustellen soll mit dieser
Fehlermeldung:


550 5.1.1 <avmb1 at firstmail.locallan>: Recipient address rejected: User
unknown in local recipient table.
  Bitte überprüfen Sie die E-Mail-Adresse des Empfängers
"avmb1 at firstmail.locallan" und wiederholen Sie den Vorgang.


Postfix ist per lda an dovecot angebunden. In dovecot sind die
(virtuellen) user in /etc/dovecot/users angelegt. Nach meinem
Verständnis sollte postfix per lda die lokalen user bei dovecot abfragen
- oder? Das klappt wohl irgendwie nicht.

Woran liegt das?


Vielen Dank im Voraus!

Tony

P. S: Ich habe die Anfrage auch unter de.comm.software.mailserver
gestellt, aber erst hinterher gesehen, das es eine postfix-Mailingliste
gibt, wo ich denke, dass die Anfrage passender ist.
